摘　　要：采用ICP-MS法测定了青海产藏茵陈中As、Pb、Cd、Hg、Cr和Cu 6种微量元素的含量,运用碰撞/反应池技术消除了Cr、As和Cu在样品中存在的潜在干扰。方法检出限为0.010～0.044 ng/mL,精密度为3.2%～6.6%,加标回收介于90%～110%之间。The elements such as As,Pb, Cd, Hg, Cr and Cu were determined in swertia mussotiifranch produced in Qinghai province. The collision/reaction cell technology was used for the elimination of potential interference. Detection limits for all elements were between 0. 010 and 0. 04g ng/mL,and the precision（RSD） was among 3.2% to 6.6% with good recovery（90% - 110% ）.
